Suppose $${\mathbf {v}}[1]=\{1\}$$. We do the proof with the help of some lemmas. Finally, we analyze a modiﬁcation of the mechanism where budget balance is achieved without designating any agent as the residual claimant.

Hence, our mechanism converges to efficiency at a linear rate as the number of agents grow. \end{aligned}$$,$$\begin{aligned} p_i(0,v'_{-i})=p_i(0,v_{-i})=p_i({\mathbf {v}})= -\frac{\theta }{n}. Hence, by Properties P0, P1, and P2, we have $$f_i({\mathbf {v}}')=0$$. (18) implies that, Using $$f_1(x_2,v_{-2})+f_2(x_2,v_{-2}) \le 1$$, we simplify this to get. Recently, studies on redistribution mechanisms have attracted increased attention in the research area of mechanism design to achieve a desirable social decision among self-interested agents. But $$v_1 > x_2$$ implies that $$f_1(x_2,v_{-2}) \ge 1-1/n$$ and $$f_2(x_2,v_{-2}) \le 1/n$$. This simplifies to $$p_i(0,v_{-i})=-\frac{\theta }{n}$$, as desired. (2), we get, where the second equality follows from step 1. We modify the dynamic pivot mechanism of Bergemann and Välimäki (Econometrica, 2010) in such a way that lump-sum fees are collected from the players. Hence, $$M^*$$ is DSIC. Now, for any $$x_2 \in (v_3,v_1)$$, Lemma 2 implies that $$f_j(x_2,v_{-2})=0$$ for all $$j > 2$$. We then move on to general mecha-nism design settings, where we prove guarantees on the social welfare achieved by Faltings’ mechanism. \end{aligned}$$,$$\begin{aligned} f_i(v_i,v_{-i}) \ge f_i(v'_i,v_{-i}).

We show that the modified mechanism satisfies ex-ante budget balance as well as ex-post efficiency, periodic ex-post incentive compatibility, and periodic ex-post individual rationality, as long as the Markov chain representing the evolution of players' private information is irreducible and aperiodic and players are sufficiently patient.

Abstract: We examine mechanism design with transferable utility and budget balance, using techniques we developed for the study of repeated games.We show that with independent types, budget balance does not limit the set of social choice functions that can be implemented.
